rlhe present invention relates to plows, more particularly to that kindof devices adapted to work the soil in separate layers or strata, Vandhas for its primary object the provision of a plow designed to break upand turn the soil in a plurality of layers or strata, and to deposit therichest and most fertile layer or stratum upon the surface and over theother layers of the worked soil.

The invention further aims to provide a plow having a forwardly andrearwardly mounted plow share, each breaking up the soil at a differentdepth to produce two separate layers or strata, and provided with amechanism by means of which the first and upper layer or top soil whichis known to be the richest in bacteria, may be deposited upon the secondand lower worked layer or sub-soil.

Another important object ot the invention resides in the provision ofthe horizontally disposed rotating disk adapted to receive the top soilworked by a first plow share and to carry and deposit the same over thesub-soil worked by a second plow share.

Other important objects and advantages ofthe invention will be in partobvious and in part pointed outhereinafter.

ln order that the invention and its mode of operation may be readilyunderstood by n those skilled in the art I have in the accompanyingdrawings, set out a possible embodiment of the invention.

in these drawings Figure l is a side elevation oi my improved plow, i

Figure 2 is a plan of the same, and

Figure 3 is adetail showing the mechanism embodied in my invention fordepositing the upper worked layer or top soil over the worked lowerlayer or sub-soil.

Having more particular reference to the drawings wherein like Charactersof reference will designate corresponding parts throughout, my improveddevice may be stated to comprise a suitably supported frame 5 consistingpreferably of parallel horizontal beams 6. To the 'forward portion ofthe frame 5 is secured a plow share 7 adapted to break up at arelatively small 301,352, ana in eer-many August 2s, 1927.

depth the upper layer .of the soil, and having a soil turning portioninwardly curved as indicated at T and more clearly shown in Figure 2 ofthe drawings. To the rearward portion of said frame 5 is fixed a secondplow share 8 designed to break up and turn over the sub-soil atsubstantially the usual depth and in the ordinary manner.

Fixed to one side of the forward portion o'f the frame 5 and extendinglaterally therefrom, is a secondary orauxiliary frame 9 wherein isjournaled a vertically mounted shaft 10 carrying at its upper end abeveled pinion 11, and at its lower end a horizontally mounted butslightly inclined disk-12 supported adjacent to the plow share 7 so asto receive the layer of top soil broken up by the plow share 7 andturned by the inwardly curved portion 7 thereof. A plate 13 is suspendedby means of bracket rods 14 atsubstantially right angles and in scrapingcontact with the upper outwardly curved face o1 the disk 12.

ln mesh with the beveled pinion 11 of the shaft 10 is a` bevel `gear 15rigid with a shaft 1G mounted transversely of the main frame 5. Alsotransversely disposed of this frame 5 is an axle 1'7 having one endprojecting laterally of the frame and carrying a driving wheel 18engageable with the ground.

Freely mounted upon that portion of the axle 17' extending between thebeams G of the iii-aine 5, is a sprocket wheel 19 adapted to be actuatedupon engagement of a clutch member 20 mounted on the axle 1'7 andoperble through any suitable means known in `he art. A chain 21 inengagement with the proeket wheel 19 and with a second sprocket fre-dtothe shaft 1('3 transmits movement o said shaft for rotating throughthe meshing bevel gear 15 and pinion 11, the shaft lOnnd therewith thehorizontally disposed disk 12 adjacent the forward plow share 7. Fromthe foregoing, it will be manifest that in providing means fordepositing the richest and most fertile layer of soil broken nl andturned by the plow share 7, upon the surface and over the sub-soilworked bythe plow share 8, l have provided device capable of mostei'lectually plowing a field.

- from the furrow II into the furrow I.

The operation of the device will be more clearly and fully understoodupon referring to Figure Q'of the dra-wings, wherein I havediametrically shown three successive furrows, I, II and III7respectively.

Still referring particularly to Figure 2, the upper layer or top soil,known to be the richest in bacteria, is broken up and turned by theforward plow share T and then directed through the inwardly curvedportion i7 of said plow share 7 in the direction of the arrow IV to thedisk 12. The disk 12 is rotated by means of the driving wheel 18 whenthe clutch member 20 isin engagement; with the sprocket wheel 19causingthe chain Q1 to transmit movement to the shaft 16 which in turn,revolves by reason of the meshing bevel gear 1G and pinion 11, the shaft1() carrying said disk 12.

The soil followingl the arrow IV, moves with the disk 1Q until itstrikes the scraping plate 13, causing the soil to be deposited on thesurface and over the sub-soil previously broken up and turned by theplow share S The vertical shaft 10 may be positioned on a slightinclineY so that the disk 2 carried thereby may tilt or incline towardsthe furrow I. The inclined position of the horizontally disposed disk 12will facilitate the distribution of the upper broken layer or top soil.In the position of the plow shown in Figure 4, the lower layer of thesoi broken up by the rearwardplow share S is turned over and depositedin the usual manner from the fur row III inthe furrow II, to besubsequently Covered as hereinbefore described by the top soil from anew furrow.

It will, therefore, be understood that in practice, the (levieewvoi'lcsover two furrows at a time. Upon making ar new furrow, the s11lrsoil isthrown into thernext succeeding Y furrow while the top soil is projectedover this latter furrow and on the surface of the second succeedingfurrow. Y

lfanifestly, the construction shown and described is capable of manymodifications and those modifications that are within the scope of theclaims.l I consider' within the spirit of my invention.

1. In a plow,v a forwardly mounted plow share for'hreaking up the topsoill` a rear-r wardly mounted plow share for breaking up the subsoil,and means associated with the forwardly mounted plow share for receivingthe top soil broken up by the latter and for depositing said broken topsoil over and upon the sub-soil broken by said rearwardly mounted plowshare.

2. In a plow, means for breaking up the top soil, means for breaking upthe sub-soil,

a substantially horizontally disposed rotata- Y supported adjacent thetop soil ble disk breaking means for receiving the broken top mames soiland depositing the same over and upon the broken sub-soil, and means forrotatingl said disk,

In a plow, a frame, means mounted upon theforward portion of said framefor breaking up the top soil, means mounted upon the rt'xarward portionof the frame for breaking up the sub-soil, a substantially horizontallydisposed rotatable disk supported adjacent the top soil lneaking meansfor receiving the broken top soil and depositing the same over and uponthe broken sub-soil, a driving wheel journaled in said frame, and meansfor transmitting movement from said wheel to the disk for rotating thesame.

et. In a plow, a frame, means mounted upon the forward portion of saidframe for breaking up the top soil, means mounted upon the rearwardportion of the frame for breaking up the sub-soil, an auxiliary framesecured to one side of the main frame and extending laterally therefrom,a rotatable disk horizontally supported in sait auxiliary frame adjacentthe forward top soil breaking means for receiving the broken top soiland depositing the same over and upon the broken sub-soil, a drivingwheel journaled in the main frame, and means for transmitting movementfrom said wheel to the disk for rotating the same.

5. In a plow, a frame, a plow share mounted upon the forward portion ofsaid frame for breaking up the top soil, a second plow share mountedupon the rearward portion of the frame for breaking up the sub-soil, anauxiliary frame secured to one side of the main frame and extendinglaterally there from: a substantially horizontally disposed but slightlyinclined disk supported in tln` auxiliary frame adjacent the forwardplow share for receiving the broken top soil and depositing the sameover and upon the broken sub-soil, a plate suspended in scrapinglcontact with the disk for distributing the broken top soil, a drivingwheel journaled in the main frame, and means for transmitting movementfrom said wheel to the disk for rotating the same.

In witness whereof I have hereunto set my hand.
